How do I prevent broken pieces and inconsistent weights when packing seeds?
Control piece breakage, segregation, poor flow and variable piece count by stabilising seeds, its supply and the pack path before reducing speed. Use net-weight, linear or multihead weighing selected around piece size, flow, fragility and target dose, then prove nozzle or discharge geometry, cutoff, fill motion and restart with real production material.
What should I check first?
Record the machine state and the finished result before changing settings. This helps identify where control is first being lost.
- Confirm the production condition of seeds: vary in size, shape, flow and surface fragility.
- Measure the limiting pack details for pouches, jars or bags, including opening, stability and fill range.
- Check that product reaches the machine through a gentle hopper feed selected for the limiting seed.
- Observe exactly when piece breakage, segregation, poor flow and variable piece count begins.
- Compare the first, middle and final part of a batch.
Why is this production problem happening?
Work from the evidence and change one variable at a time. These are the most relevant causes to investigate first.
- The selected method does not accommodate that seeds is vary in size, shape, flow and surface fragility.
- Product condition changes between the sample, start-up and a sustained run.
- Pack tolerance or presentation is influencing the measured result.
- The process is amplifying piece breakage, segregation, poor flow and variable piece count.
- The outlet or pack geometry is unsuitable.
How can I correct or improve it?
Make a controlled change, repeat the same measurement and compare the result before moving to the next adjustment.
- Trial seeds using representative production batches and the full pack matrix.
- Use net-weight, linear or multihead weighing selected around piece size, flow, fragility and target dose.
- Plan changeover around this requirement: dry-clean between varieties and control cross-mixing.
- Change one controlled variable at a time and record the result.
- Confirm the correction during a sustained run.
What should I send Lancing?
The most reliable recommendation is based on representative production materials and a measurable acceptance result.
- Representative sample of Seeds
- All relevant pouches, jars or bags
- Target fill and tolerance
- Required accepted output
- Photographs or video of the current process
- Representative product sample and safety information
- Bulk density range, particle size and flow observations

What should I check first for seeds?+
Confirm the production condition of seeds: vary in size, shape, flow and surface fragility.
Why does this problem happen with seeds?+
The selected method does not accommodate that seeds is vary in size, shape, flow and surface fragility.
How can I improve or correct the problem with seeds?+
Trial seeds using representative production batches and the full pack matrix.
Which part of the production line does this question relate to?+
This question relates primarily to powder & granule handling. It may also be affected by upstream product or pack supply and by downstream handling, so check the full production sequence rather than one machine in isolation.
What should I send when asking for a machinery recommendation?+
Send Representative sample of Seeds; All relevant pouches, jars or bags; Target fill and tolerance; Required accepted output. Representative production samples and a measurable acceptance target are normally more useful than a catalogue description alone.
